Aluminum electrolytic capacitors are widely used in various fields. ALC10A471EH550 is one of the most common used type. This article will discuss on its application field and working principle.

First of all, let’s summarize the basic information about ALC10A471EH550. It is a non-polarized aluminum electrolytic capacitor with a rated voltage of 100V, which is designed for high input/output voltage applications. Its max. surge working voltage is 630V, and it can handle temperature ranging from -40℃ to +105℃. ALC10A471EH550 is particularly suitable to be used in DC and AC filtering, snubber and bypass purposes.

Now let’s address its application field. Generally speaking, ALC10A471EH550 can be used in most electronic components, such as lamps, relays, starters, electronic door locks, TV sets, video tape recorders and car audio systems. Furthermore, because of its high surge working voltage and high temperature tolerance, ALC10A471EH550 is particularly suitable to be used in AC / DC motors, transportation communication and security components as well.

Next, let’s discuss on its working principle. Fundamentally speaking, ALC10A471EH550 is composed of two thin, aluminum foil electrodes and a layer of electrolyte. The two foils are separated by the electrolyte, and current flows through the gaps. This current is stored as an electric charge on the capacitance plates. When the applied voltage reaches the preset level, electric field lines will be generated between the two plates, and this will result in the capacitance voltage being discharged.

Moreover, what also needs to be mentioned here is that, as a polarized capacitor, ALC10A471EH550 needs to be connected correctly. It requires that the anode is connected to the positive voltage and the cathode to the negative voltage. Reverse connection may lead to capacitor damage.

In conclusion, ALC10A471EH550 is an excellent non-polarized aluminum electrolytic capacitor that is widely used in various fields, such as lamps, relays, starters and AC / DC motors. Its working principle is based on the electric field generated between two charged plates. Furthermore, due to its high surge working voltage and temperature tolerance, it is particularly suitable to be used in transportation communication and security components. Last but not least, proper connection is necessary to make sure the capacitor works successfully and safely.
